How to get existing layerfilters

[EnM4st3r]

Hi, 

 

does anyone know how to get a list of all Layerfilters in the document?
I want to create a new Filter but if that filter already exists i want to add the layers to that filter instead of creating a new one.

Thats the line im using to create the filter:

(command "_.-layer" "_filter" "_new" "_group" "" (apply 'strcat (mapcar '(lambda (x) (strcat x ",")) laylist)) filtername "")

(setq xdict (vlax-vla-object->ename
	      (vla-getextensiondictionary
		(vla-get-layers (vla-get-activedocument (vlax-get-acad-object)))
	      )
	    )
)
(vl-remove-if '(lambda (x) (/= 3 (car x))) (dictsearch xdict "ACAD_LAYERFILTERS"))

hmm, somehow my layerfilters doesnt seem to be saved in there.

 

  (setq xdict (vla-getextensiondictionary (vla-get-layers (vla-get-activedocument (vlax-get-acad-object)))))
  (vlax-dump-object (vla-item xdict "ACAD_LAYERFILTERS") t)

 

this gives me Count 0 even tough there are layerfilters
